Sandy Mazzella was the president of Advanced Mowing and Landscaping Inc., and he was business partners with Sander.

Officials said Stephanie Mazzella was an ICU nurse at WakeMed. A hospital spokeswoman said Mazzella began working at WakeMed in 2008.

The shooting may have stemmed from an earlier dispute between the neighbors, officials said. Deputies responded to the homes of the two parties around 9 a.m. on Friday.

Sander was previously charged with communicating threats toward the Mazzellas in February. The 52-year-old threatened to "put them in a box," according to arrest warrants. Sander was due in court April 1 for the charges last month.

According to court documents, Sandy Mazzella was charged with misdemeanor stalking on March 3, with an offense date of Feb. 27; the complaint was filed by Lori Botti, president of Advance Patio and Landscape Inc. Stephanie Mazzella was the vice president of the company.

Botti and Sander were also co-plantiffs in a case suing Sandy Mazzella for "money owed," totaling less than $10,000 on March 2, according to court documents.

​"There were two law enforcement officer vehicles in the driveway, and you notice it because you don't see that much around here," said neighbor Anthony Horne. "This is a really quiet neighborhood, people keep to themselves."

No details were released on how the Friday morning dispute was resolved.

"It sounds like it has been an ongoing feud between the neighbors for a while," Harrison said.

No additional information has been released. Officials said an investigation is ongoing.

This is horrible. I wonder what was so important that they argued for months, the suspect had communicated threats charges filed against him that should have been taken more seriously. What then it lead to murder? This is definitely going to be on When Neighbors kill show on investigation discovery

I don't really like judging people but look at Sander's facebook page. It screams dbag. I feel sorry for his young children and the victims though.

Wait! Either he came out and went back in OR he "did not come out to start with". Which is it?

I read that to mean after he went back into his house, it appeared he may not come out, but then he did come out and surrender to police.
